So far I'm going to stick to my build, I don't like that H61 MB either. Big reasons are no SATA 6 gb/s and it doesn't look like it has any chassis fan connections.
I like nVidia and the case I found has a top vent.
Any thoughts on the hybrid drive or if 500W should be enough?
Call me crazy... but to my knowledge chassis fans don't connect to your motherboard.
